"You go from 100-million-year-old shell fossils from the inland sea, to 95-million-year-old dinosaur fossils, to plant fossils that show the period when Australia was covered by rainforest, right through to the rise of the megafauna and even the present day arid zone species," he said.

"During periods of drought it's a great time to find fossils, and to prepare them and to create a resource for the tourism industry."
